The death toll from the California wildfires has risen to 80, authorities said. The number of people missing also rose sharply, to nearly 1,000.

The Camp Fire in Northern California destroyed an entire town in less than a day and has killed at least 77 people, making it the deadliest fire in the state's history. It was 66% contained on Monday morning.

The Woolsey Fire, on the outskirts of Los Angeles, has burned more than 150 square miles and is over 90% contained.

California wildfires are becoming so frequent and pervasive that local officials say there's almost no need for the term "wildfire season" anymore.

The flames from California's deadliest wildfire have mostly moved into forested, unpopulated areas of the state, but the death toll is still rising.

The remains of a handful of people were found over the weekend, bringing the total number of deaths from Northern California's Camp Fire to 77.

President Donald Trump visited the wreckage in Paradise, California on Saturday, describing the area as "total devastation."

"We're going to have to work quickly," he said. "Hopefully this is going to be the last of these because this was a really, really bad one."

The Camp Fire continues to rage across Butte County, less than 100 miles north of Sacramento, though it is 66% contained.

The other deadly wildfire in California, the Woolsey Fire, has burned more than 150 square miles in the hills around Los Angeles, and is close to extinguished. Residents of Malibu and other LA suburbs whose houses were in the path of the fire have begun to return home to charred shells.

Two people were killed in the Woolsey Fire on November 9, and a third body was found in a burned home in Agoura Hills on November 14, bringing the death toll from both the Woolsey and Camp fires to 80.

Coroner search teams are searching for victims in Paradise. More than 450 people were assigned to search for human remains in the debris, the AP reported. Abandoned cars in driveways can be a sign that residents might not have escaped in time.

Sifting through the ashes, the teams sometimes recover only the partial remains of a victim to place in a body bag.

Butte County Sheriff Kory Honea said the county was working with anthropologists from California State University at Chico to help identify bone fragments among ash in the area.

Fortunately, there's rain in the forecast this week, but Cal Fire doesn't expect the Camp Fire to be extinguished until the end of November. Search crews are worried that when it rains, mud and puddles will make sifting for remains even trickier.

Federal assistance is coming, but Trump has blamed a lack of raking for the fires

Governor-elect Gavin Newsom declared a state of emergency in Butte County the day the fire broke out and sent a letter to President Donald Trump and the Federal Emergency Management Agency asking for federal assistance.

Trump said in a tweet last Monday that he approved an "expedited request for a Major Disaster Declaration," which allows people whose homes or workplaces were hit by the Woolsey or Camp Fires to apply for federal assistance.

FEMA said in a release that federal disaster assistance "can include grants for temporary housing and home repairs, low-cost loans to cover uninsured property losses, and other programs to help individuals and business owners recover from the effects of the disaster."

Many fire victims have next to nothing left. Troy Miller, a Butte County resident, is camping in a truck next to the remains of his house in Concow.

"I'm alive and I'm still up here," Miller told the Associated Press. "There are plenty of other people worse off than I. I've got a lot of faith in God. I think things will be OK."

Before Trump left for California, he told reporters that he would be "talking about forest management" with Newsom and Gov. Jerry Brown. He also criticized Californians for not doing more raking before the fires broke out, and suggested that's how effective forest fire prevention works in Finland. The president of Finland says it's not.

"I was watching the firemen the other day, and they were raking areas — they were raking areas where the fire was," Trump said on Fox News Sunday. "That should have been all raked out and cleaned out," he added. "You wouldn't have the fire."

Smoke from the Camp Fire is also making it difficult for people to breathe, since soot has blanketed wide swaths of Northern California. On Monday, the air in the San Francisco Bay Area — more than 150 miles from the flames — was classified as "unhealthy."

Over the past few days, firefighters strengthened their hold on the flames — the fire was 94% contained on Monday.

Red-flag warnings that were in effect around Southern California last week have expired, giving firefighters a boost as winds die down.

Three people died in the Woolsey Fire. Two burned bodies were found in a car in Malibu near Mulholland Highway, the Los Angeles County Sheriff's Department said, while a third victim was discovered in the wreckage of a home in Agoura Hills.

At its peak, the fire forced over 275,000 people from their homes. Carol Napoli, who lives at the Vallecito mobile-home park for seniors in Newbury Park, told the AP that the flames approached the park so fast that her mother didn't have time to grab her oxygen tank before they bolted in a car.

"We drove through flames to get out," Napoli said, adding: "My girlfriend was driving. She said, 'I don't know if I can do this.' ... Her son said, 'Mom you have to — you have to drive through the flames.'"

The fire has threatened mobile homes and mansions alike. Celebrities including Gerard Butler, Miley Cyrus, and Neil Young lost their houses.

Another smaller fire in Southern California, the Hill Fire, charred over 4,500 acres but was extinguished on Friday, November 16.

The Woolsey and Hill Fires threatened the town of Thousand Oaks, where residents were already reeling from a mass shooting that left 12 people dead last week. Three-quarters of Thousand Oaks residents were under evacuation orders over the weekend, according to the AP.

A resident named Cynthia Ball told the AP it was "like 'welcome to hell.'"

The LA County website says: "If you are affected by the Woolsey or Hill fires, the Thousand Oaks mass shooting, or both, you can call the Disaster Distress Helpline at 1-800-985-5990 or text 'TalkWithUs' to 66746 for emotional support and resources."

Wildfires are no longer limited to one season

The flames in Southern California have been fueled by hot, dry conditions and spread by Santa Ana winds, which tend to blow in from the desert in the fall months.

Wildfire season in California technically runs from late summer through the fall. But as the planet heats up, higher-than-average temperatures and drought conditions are becoming more common. Meanwhile, developers continue to build homes in places that are naturally prone to wildfires.

"Whether it is to allow a rock star to build on a ridgeline in Malibu or a manufactured-home community that nestles into the foothills, the decision is the same and the consequences are the same," Char Miller, the director of environmental analysis at Pomona College, told the Times.
